IMPROVEMENT :N Devices Fon verw-infirme HATS.

Specification forming part of Letters Patent No. 50.999. dated November2l, 1865.

Toall 'whom it may concern:

Be it known that we, .D. K. ALBRIGHT, of

.Phil-adelphia, Pennsylvania, and L. H. `DE

ted States were granted to us on the 13thv day ot' J une, 1865 and ourinvention consists in the combination, with abat enlarged near the brim,ot' a series of blocks or projections arranged within the enlargedportion of the hat-so that the head of the'wearer will be mains tainedfree fro1n'-eontact with the side of the enlargement, thus leaving-aspace between the latter and the head through which the air cancirculatefrecly.

In order to enable .others skilled in the nrt to make our invention'welwill now proceed to describe the manner ot' carryingl the same intoeffect.

0n reference to the accompanying drawings,

which form a part of this specification, Figure lis asection of ourimproved hat, and Fig.v2, an inverted plan view.' A is the body ofthehat, and Bist-he brim, the lower portion ofthe body between lthepoint a: and the point where it'meets the brim, 'iucreasing in diameterS'o'as toform an enlarge-1 ment ot;` the character show-nn'theidrawings.

, To the inner side of this enlargement arese- *cured blocksor sectionsD, of *felt or otherv suitable material, .theisaid blocks being ar- 4,ranged at intervals withinthe enlargement, as shown in'Fig. 2. y Whenthe hat is placed upon lthe head of the wearer only the sides of theblocks-Dwi1l bear against thesame, so thatthe air maypss freely, between.the blocks 'into the enh. gement() and into the .body ofthe hat labovethe head such a constant circulation of fresh air being thus maintainedas will prevent the head from being uncomfortably heated.

It will be apparent that a hatpof this chary acter may be manufacturedatless cost' than th'osc in which corrugated vbands and similarexpensive and but partially elcient devices are used, and it will alsobe seen that a hat so constructed' is far superior to those referredto'. inasmuch as the a'ir is. admitted in much larger quantities, andcan circulate with greater freedom over the head of thewearer andbetween the latter andf the hat.. It willalso be seen that bythisarrangement of the blocks within the enlargement the hat willaccommodate itself readily to the form of the head` Although we havedescribed blocks D of felt or other similar material as being u sed, thesame result will be obtained by bending thin metal plates Dto the formshown' in Fig.`2

and securing them within the enlargement in the sam'e position as theblocks. We donot wish to confine ourselves, however, to either theplates or blocks,as projections of any suitable material bearing againstthe head s'o as to form a space between the latterand the inner side ofthe enlargement may be used.

lf desirable, also, a sweat-band X may he secured to the inner ysides ofthe blocks orprojectionsD.

We claim as our invention and desire to secure by Letters Patent- Thecombination, with a hat enlarged near tue brim, of a series of blocks orprojections D, arranged within the enlarged portion of thehat,substantially as described, tor the purpose speqiell.

In testimony whereof we have signed our names to thiS;8.Pecitcation inthe presence ot' two 'subscribing witnesses.
